Test ID:1.3.6.1.4.1.25623.1.0.61723
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2008:0965
Summary:NOSUMMARY
Description:Description:

The remote host is missing updates announced in
advisory RHSA-2008:0965.

Lynx is a text-based Web browser.

An arbitrary command execution flaw was found in the Lynx lynxcgi: URI
handler. An attacker could create a web page redirecting to a malicious URL
that could execute arbitrary code as the user running Lynx in the
non-default Advanced user mode. (CVE-2008-4690)

Note: In these updated lynx packages, Lynx will always prompt users before
loading a lynxcgi: URI. Additionally, the default lynx.cfg configuration
file now marks all lynxcgi: URIs as untrusted by default.

A flaw was found in a way Lynx handled .mailcap and .mime.types
configuration files. Files in the browser's current working directory were
opened before those in the user's home directory. A local attacker, able to
convince a user to run Lynx in a directory under their control, could
possibly execute arbitrary commands as the user running Lynx. (CVE-2006-7234)

All users of Lynx are advised to upgrade to this updated package, which
contains backported patches correcting these issues.

Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
